Filed may '9, 1928 RAYMUMJ: E. Manna- BY ATTORNEY Patented Feb. 2, 1932UNITED STATES PATENT OFFICE RAYMOND G. MOORE, OF BRIDGEPORT,QONNECTIGUT, ASSIGNOR TO THE BASSICK COM- PANY, 'OF BRIDGEPORT,GON'N'ECTICUT AUTOMOBILE DOOR LATCH Application filed May 9,

The present invention relates to an im: proved automobile door latch,particularly of the type having an inside and an outside operatinghandle, and in which the outside handle is adapted to be locked againstoperation by manipulation of the inside handle. The latch is especiallyadapted for use upon doors of closed cars, being applied to all bug oneof the doors, and which latter is adapte to be locked from the outside.I particularly propose to provide an outside handle rollback adapted tooperate directly upon the latch bolt,,and-an inside handle roll-backadapted to operate upon the. latch bolt through an intermediate memberdirectly engaging the roll-back, and further to provide saidintermediate member in such relation to the outside handleroll-back.that by manip- V at any desired points without changing theirmain combinative relation, or materially al-.

tering the design of the parts, thereby adapting the main parts ofthelatch to use upon various car doors, in which the positions of thehandles are differently arranged; and as one embodiment, I propose toprovide a remote control inside handle roll-back adapted go be placed atany desired point on the'door rame.

With the above and other objects in view,

embodiments of the invention are shown in the accompanying drawings, andtheseembodiments will be'hereinafter' more fully de scribed withreference thereto, and the invention will be finally pointed out in theclaims.

In the drawings:

Fig. 1 is aplan view of an automobile door latch, according to oneembodiment of the invention, the dotted lines showing the parts SerialNo. 276,400.

in the relation in which operation of the outside handle is prevented,the cover plate being shown in dot-and-dash lines;

Fig. 2 is a plan view of a modified form of the invention, showing indotted lines both the relation of the parts for preventing operation ofthe outside handle, and theretracted relation of the latch bolt throughmanipulation of the inside handle roll-back;

3 is a sectional view, takenalong'the line 33 of Fig. 2. i

Similar reference characters indicate corresponding parts throughoutthe, several figures of the drawings.

Referring to the drawings, and more particularly to Fig. 1 thereof,theembodiment of the invention shown therein comprises a sheet metalframe. or base plate 10 having a face flange 11 bent therefrom at oneend, within which a rectangular opening 12 is provided, a flange lipportion 13 of the metal cut from said opening being bent inwardly inparallel spaced relation to the plate 10 to form a bearing for the latchbolt.

The latch bolt comprises a nose portion 14, riveted at 15 to a sheetmetal bolt plate 16, provided near its inner end with a pressed out boss17 engaged in a guide slot 18 provided in the plate 10, a coil spring 19engaged with the inner end of said bolt normally pressing it to itsprojected position. The bolt is retained against displacement by meansof a flat cover plate 20, (shown in dot-and-dash lines) flanged at itsupper and lower edges, as at 21, and secured to the plate 10 by lugs 22inserted through slots 23 in said plate, and bent over upon the surfacethereof.'

The lower edge of the bolt is provided near its forward end and inspaced relation to the face flange 11 with an outer handle roll-backengaging lug or projection 24, and rearwardly thereof with an elongatedrecess 25 having a lug portion 26 atthe inner end of thebolt adapted forengagement by the intermediate member, presently to be more fullyreferred The outside handle roll-back 27 has its hub 28 rotatablyengaged in apertures formed in. the plates 10 and 20 adjacent the flange11,

and is adapted to actuate the bolt through engagement with the lugextension 24. A lug projection 29 on the hub of the roll-back, having ahorizontally disposed lower face, is

adapted, as will hereinafter more fully ap-.

pear, to be engaged by the intermediate member to prevent operation ofthe outside handle roll-back.

The intermediate member consists of a flat sheet metal bar 30, disposedupon the plate 10 below the bolt for longitudinal movement, beingprovided with pressed out bosses 31 and 32 engaged in longitudinal guideslots 33 and 34, respectively, and retained against displacement by thecover plate. At its upper edge the bar 30 is provided with a lugprojection 35 engaged in the recess 25 of the bolt and normally bearingagainst the lug 26. At its lower edge and at its forward end the bar isdownwardly offset, as at 36, and is provided with a forwardly projectinglug 37, normally free of the lug 29 of the outside handle roll-back, butadapted, upon forward sliding movement of the bar 30, to engage beneathsaid lug 29 to thereby prevent operation of the outside handleroll-back. A spring 38 secured to the plate 10 yieldably engages thelower edge of the member 30 and is adapted through engagement in notches39 and 40 formed therein to yieldably retain said member in its normalposition, and in its forwardly moved outside handle roll-back lockingposition.

The inner end of the member 30 projects rearwardly from the casing, andis pivotally connected to one end of an elongated link 41, the other endof which is pivotally connected to the remote control inside handlerollback lever 42, the hub 43 of which is rotatably mounted in a frame44, adapted to be secured upon the door frame at any desired point.

The operation is as follows:

As shown in full lines the parts are in their normal relation,retraction of the latch bolt being eifected independently by either theoutside handle roll-back, or the inside remote control roll-back lever,the latter operating through the intermediate member 30. In order toprevent actuation of the outside handle roll-back. the inside handleroll-back lever 42 is moved in the opposite direction from its boltretracting direction, sliding the member 30 forwardly, as indicated indotted lines, and engaging the lug projection 37 beneath the roll-backlug 29, the spring 39 yieldably retaining the parts in this relation.The outside handle is thus blocked against operation. 4

The normal operative relation is restored uponmoving the inside handlein retracting direction, the initial movement bringing the lugprojection 37 out of the path of the lug 29, and the continued movementcausing retraction of the bolt.

Under all conditions the latch bolt is free to be retractedindependently of the handles, that is, by pressure directly applied tothe nose'end, as in slamming the door closed.

In Figs. 2 and 3 I have illustrated a modified form of the invention inwhich the inside handle roll-back is mounted directly on the latch ease.The member 30 is shorter than in the first embodiment, terminatingwithin the case, and is provided in its lower edge with a recess 45engaged by the rounded upper end 46 of the inside roll-back lever 47,the hub 48 of which is rotatably mounted in apertures provided in thebase and cover plates 10 and 20. A spring 49 mounted on the base 10engages notches 50 and 51 in the edge of the roll-back, to yieldablyretain the parts in their normal position and in the outside handleroll-back locking position, this latter position being shown by theheavy dotted lines. The light dotted lines indicate the retractingposition by manipulation of the inside handle. 4

The operation is the same as in the first embodiment. 1

I have illustrated and described preferred and satisfactory embodimentof the invention, but it will be obvious that changes may be madetherein, within the spirit andscope thereof, as defined in the appendedclaims.

Having thus described my invention, what I claim and desire to secure byLetters Patent 1s I 1.
